PreparedStatement.getParameterMetadata Not Reporting Query Statement Types Correctly

PreparedStatement.getParameterMetadata is not reporting metadata information correctly. Once returned, Parametermeta only correctly reports the number of parameters a statement contains. It does not report type information correctly - all types are returned as String.

Is there a suggested way to get ParameterMetadata in the absence of the API returning it using PreparedStatement.getParametermetadata.

Example program attached which exhibits the outlined behaviour above. Executed against MariaDb 10.2.1 on Windows 10 using client driver 2.2.1.

Sample output from execution of test program
